Hopgood started his career in British comics getting work at 2000 AD and Marvel UK from the mid-1980s onwards on titles like Tharg’s Future Shocks, Spider-Man and Zoids, and Action Force.
At Marvel Comics in the early-1990s, he was the main artist on Iron Man where, with writer Len Kaminski, he created War Machine f(James Rhodes had appeared earlier, but the alias “War Machine” and the armour were created by Hopgood/Kaminski). War Machine later received his own eponymous series and appeared in the feature films Iron Man and Iron Man 2.
Hopgood took a break from comics following his Iron Man run, working in computer games for three years. His most notable credit during this time is on the space shooter Blast Radius published by Psygnosis. Hopgood returned to British comics in the mid-late 1990s with a run on the rebooted Harlem Heroes story at 2000 AD and the Warhammer Fantasy series Darkblade for Games Workshop with writer Dan Abnett. He worked again with Abnett on the Warhammer 40,000 comic Exterminatus at Boom! Studios, where he also worked on Defenders of Ultramar with Graham McNeill.
His most recent comics work includes the Roman monster hunter story Legion Zero for Aces Weekly, a Doctor Who story for IDW and The Man from the Ministry written by Gordon Rennie and appearing in the Judge Dredd Megazine. He revisited War Machine recently with a “cutaway” style illustration for the Marvel Fact Files published by Eaglemoss. Hopgood continues to work as a freelance illustrator working primarily for children’s and educational publishers.
